Profiling based optimization means better performance.

Here’s phk’s suggestion:

We can compile our kernel with "--test-coverage --profile-arcs" to
do basic-block profiling (see kernbb(8) and gcov(1)/gcc(1) docs.)

www.delphij.net receives tenfold of increase in uptime by migrating to FreeBSDChina's machine

The migration apparantly gots its result, 30 times of increase here. No old hardware any more!!
